In addition, (1) the power generating unit to generate the primary deceleration by adopting the geared motor or the manual drive unit to generate the primary deceleration by adopting the worm gear, (2) the main deceleration unit to generate the main deceleration by forming the planetary gear, (3) the second deceleration unit that generates secondary deceleration in the third and fourth axes, and (4) the actuator can be miniaturized by implementing the deceleration required in the double worm rack unit in various forms. By implementing 15 tons, which is the limit of the opening and closing capability of rack and spindle type actuators with gear arrangements up to 100 tons, the actuator provides a very economical opening / closing capability and expands the width corresponding to the needs of the gate's opening and closing capability. To provide.

In addition, by operating the self-loading lower portion with the operation lever formed to move the 2-1 axis through the spline in the axial direction to release the multi-plate clutch 408 to immediately implement the weight drop impossible in the conventional spindle-type switchgear body By quickly and safely self-weight (120) to shorten the closing time of the waterway to provide the effect of minimizing the damage caused by flooding.

In addition, when the power generation unit cannot be driven due to a power failure caused by an abnormal weather such as a heavy rain typhoon, which occurs unexpectedly, it provides an effect of preventing floods by manually opening and closing the water gate by driving the manual control unit.

In addition, when the overload acts on the drive shaft by the torque control device formed on the self-weighting actuator and the organic control part of the hydrophobic fish, the power generator automatically cuts off the power or changes the running direction of the water gate, Providing immediate and safe protection of hydrostatic hoist, it minimizes damages caused by large floods such as flooding of rivers, loss of farmland due to the collapse of frozen bodies and flooding of lowlands.

In addition, when installing a plurality of gates in one place of the same channel or installing multiple gates in several places at the time of opening / closing of the main body of the body, the real-time torque acting on each of the self-weighting actuators and the information necessary for the various gate operations are acquired. In order to centralize management of multiple gates installed at one place or multiple gates at several places, the torque control unit and the hydrophobic fisherman are combined to enable the operation of the gates quickly and remotely. It provides the effect of preventing floods by quickly operating the floodgates in case of abnormal weather such as reducing rainstorms and unexpected heavy rain typhoons.
